Binding Energy Per Nucleon
Key Stage 5
Meaning
The binding energy per nucleon is the average work done per nucleon to separate a nucleus into its constituent parts.
About Binding Energy Per Nucleon
- Calculated as the total binding energy of the nucleus divided by the mass number.
- Highest for nuclei with a mass number around 56 (iron).
- Indicates how tightly nucleons are held together in the nucleus.
- Affects the energy released in nuclear reactions.
Examples
- Iron-56 has the highest binding energy per nucleon, making it the most stable nucleus.
- Uranium-235 has lower binding energy per nucleon, making it suitable for fission.
